Hi Qian. Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Hi Qian. Many thanks. Regards. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Hi Qian. I just paid attention to the fact that the the backtrace file that should have been generated with report and automatically uploaded as an uncompressed attachment is missing (unless you unchecked the "backtrace" checkbox before submitting the report). Please could you kindly go for it? You can find the backtrace file into /var/cache/abrt/ccpp* directory corresponding to the day that the crash occurred. In case you had several in the same day, look for the one containing. -------------------------------------- backtrace ----- Core was generated by `compiz --ignore-desktop-hints glib gconf gnomecompat'.

Created attachment 374163 [details] /var/cache/abrt/ccpp-1258442865-1676/coredump Hi, Hamidou: I found a file named coredump in the dir. I think that's the file you need. because there's another file named backtrace in the dir but containing few information,I'll show it below: Core was generated by `compiz --ignore-desktop-hints glib gconf gnomecompat'. Program terminated with signal 11, Segmentation fault. #0 doPoll (timeout=<value optimized out>) at display.c:1209 in display.c Thread 1 (Thread 1676): btw,I didn't uncheck the "coredump" checkbox before committing, maybe because of my poor network environment. well,anyway I'll upload the coredump for you.
Ok. So I have the BT file. But it looks like truncated. ------------------------------------------------------------------------- BFD: Warning: /home/liveuser/Downloads/core is truncated: expected core file size >= 28692480, found: 962560. Core was generated by `compiz --ignore-desktop-hints glib gconf gnomecompat'. Program terminated with signal 11, Segmentation fault. #0 doPoll (timeout=<value optimized out>) at display.c:1209 1209 for (i = core.nWatchFds - 1, w = core.watchFds; w; i--, w = w->next) (gdb) bt Cannot access memory at address 0xbfcc7adc (gdb) print i $1 = <value optimized out> (gdb) print w $2 = (CompWatchFd *) 0x10 (gdb) print (w->next) Cannot access memory at address 0x10 -------------------------------------------------------------------------- So not sure it is going to be exploitable. Qian, could you check the file size on your computer ? If you have [liveuser@localhost ~]$ ll Downloads/core -rw-rw-r--. 1 liveuser liveuser 962560 2009-11-27 15:55 Downloads/core It means that it is incomplete. And in this case we will leave this up to the maintainer (Adel) to decide whether or not this can be pushed forward anyway or not. In the case that your file in local is complete, I really invite you to try upload the file again, and check the size as reported by the bugzilla ticket to know if you succeeded. Thanks in advance. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
As well, do you remember if a special action triggered this issue or if it occured -randomly-? Thanks
Hi,Hamidou: the file I uploaded is the same size as my local file. -rw-r--r-- 1 root root 962560 11月 27 16:37 coredump I think you're right,I checked backtrace and coredump files in other dirs, this coredump is much smaller than other coredump files. I don't remember how this bug was triggered.the OS Fedora12 on my machine is upgraded from Fedora11.
Hi Qian. Sorry to come late. Many thanks for the upload attempt and the information. This issue does looks like a 100% compiz related. I hope that the maintainer would have enough information in order to fix this issue (not sure). @Adel: Assigning to you (from NEW to ASSIGNED).
